Access issues typically fall into two categories. The most likely is you lose or replace your verification method — for example, you get a new mobile phone or computer and need to switch your authenticator app or built-in authenticator to your new hardware, or you lose your security key and replace it with a new one. Another possibility is that the connection between your verification method and your Salesforce account stops working. In these cases, the way to restore MFA login access is to disconnect the affected verification method, then either reconnect it or register a replacement method instead.

• If you're not able to log in to complete this task, ask your admin for a temporary verification code.
• If you have trouble disconnecting a verification method, you can ask your admin to disconnect it for you.
• Consider registering two or more verification methods so you have backup options if something happens to your primary method.

The steps for this task depend on the type of verification method that you’re using.
